Oral Health Quality of Life (OHQoL) Was Assessed

Full-arch implant-supported fixed dental prostheses are a widely accepted treatment for edentulous patients, with high long-term implant survival rates. However, further research is needed on longer-term patient satisfaction and on the psychosocial impact of this treatment on patients' daily life and functioning. Assessing patient-reported outcomes - oral health-related quality of life (OHRQoL) and patient satisfaction - allows the impact of full-arch rehabilitation on patients to be evaluated.

The distribution- and anchor-based methods will be used to estimate the Minimal Important Difference (MID) of the OHIP-P-HIN. Two established distribution-based approaches, the standardized effect size (ES) and standardized response mean (SRM) will be calculated. The ES is calculated by dividing the mean change scores in the OHIP-P-HIN from baseline by the standard deviation of the baseline scores. And the SRM are computed as ratios of the mean change score divided by its standard deviation. The anchor-based approach will be applied by using the global transition scale as the anchor.
